Abstract: A communication method and a device are provided. The method includes: Two thresholds are set on a terminal device side: a first threshold and a second threshold. A terminal device may determine a cause for a radio link failure RLF based on a value relationship between a measurement result of a radio signal and the two thresholds, and further may use different handling manners depending on different RLF causes. According to the foregoing method, the terminal device can more accurately locate the cause for the RLF, and perform corresponding handling, to quickly resume communication, meet a service requirement of an industrial scenario, and the like.

Abstract: This application provides a communication method and a communications apparatus. The communication method includes: determining, by a transmit end device, a first moment, where the first moment is a moment when a receive end device needs to deliver first data to an upper layer of a communications protocol layer of the receive end device; and sending, by the transmit end device, first indication information and the first data, where the first information is used to instruct the receive end device to deliver the first data to the upper layer of the communications protocol layer of the receive end device at the first moment. The receive end device can be supported in determining the first moment based on the first indication information and delivering the first data to the upper layer of the communications protocol layer at the first moment.

Abstract: The present disclosure provides a data processing method, a node, a structure, and an apparatus. The method includes: receiving, by an aggregation node, a first non-access stratum message sent by user equipment (UE), where the aggregation node includes at least two types of interfaces, and each type of interface is used to receive a first non-access stratum message of one radio access technology (RAT) type; converting, by the aggregation node, the first non-access stratum message into a non-access stratum message in a first format based on a RAT type of the first non-access stratum message, where the first format is a non-access stratum message transmission format supported between the aggregation node and a core-network control plane entity; and sending, by the aggregation node, the non-access stratum message in the first format to the core-network control plane entity. A sink design of the aggregation node saves sending and receiving resources of a core network and improves packet forwarding efficiency.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for semi-persistent scheduling (SPS). The method for semi-persistent scheduling includes: interacting, by a first user equipment, with a base station to obtain an SPS resource allocated by the base station; performing, by the first user equipment, device-to-device (D2D) communication with second user equipment by using the SPS resource; and after the D2D communication ends, sending, by the first user equipment, release indication information to the base station, so that the base station releases the SPS resource. In embodiments of the present disclosure, after D2D communication ends, the first user equipment sends a release indication message to a base station, so that the base station can release an SPS resource, preventing waste of resources.
